Re: [Netconf] Netconf Light or Netconf for constrained devices

Bert,

I am interested in a NETCONF-lite for constrained devises.  However, I worry about approaches that either baseline at either a) NETCONF- zero with vendors adding whatever features they think appropriate  or b) NETCONF with vendors subtracting whatever deviations they think appropriate.   I would, for simplicity sake, prefer the expertise in the WG to define a baseline NETCONF-lite feature set that I could easily explain to my acquisition and procurement folks.

Thanks,  Bob

Subject: [Netconf] Netconf Light or Netconf for constrained devices

We would like to encourage the WG participants to
engage in a discussion on how to allow for
the use of NetConf for constrained devices.

See below the summary of our discussion at this weeks
session in IETF83.

Please express your opinions and pls describe
the pros and cons (as you see them) of each
possible approach.

It might also be good if someone (Andy?) could
summarize/describe how exactly one can in fact support
constrained devices with standard Netconf plus
a "deviations" approach. Maybe an example would be
the best way to demonstrate how that would be done.
